The Seasonic M12 II Bronze Evo Edition excelled in our tests, achieving some fantastic technical results under demanding situations.
The appearance of the M12 II Evo Edition is immediately reassuring – the quality of finish easily achieves the standard we would expect from Seasonic. The bundled cables are very high grade and with six 6+2 pin PCIE cables included there is plenty of potential for a high specification SLI or Crossfire system build.
The pure modular design will appeal to the demanding enthusiast audience who are building a showcase system complete with backlit window panel. The adoption of flat ‘ribbon' style modular cables ensures that routing will be straightforward.
Technically the unit is exemplary. Load regulation is rock solid and it dealt with our intensive cross loading test without a hitch. Noise suppression is excellent and all rails fall well inside industry tolerance guidelines. Our testing showed that the unit is over specified and we were able to hit around 960W before the unit shut down safely. The use of high grade 105c rated Japanese capacitors is always a plus point, especially if you live in a warm climate.
The Seasonic M12 II Bronze Evo Edition achieved close to 80 Plus Silver certification in our tests, well ahead of the 80 Plus Bronze claims.
The supply isn't the quietest we have tested although under most circumstances it doesn't emit a lot of fan noise. With a 700W+ load demand the fan can be heard, although the pitch of the rotor rotation is low, so it isn't distracting.
Pricing in the United Kingdom hasn't been confirmed but Seasonic told us they expect the unit to be priced below £130 when it ships in the coming weeks. A 750W unit will also be released in this range, but we have no pricing information yet for that model.
Pros:
- Strong ripple suppression.
- deep paint.
- 105c japanese capacitors.
- achieved 80 Plus Silver efficiency in our tests.
- delivered 964 watts before shutting down.
- fully modular.
- flat cables.
Cons:
- Won't be cheap.
Kitguru says: Another stellar power supply from the Seasonic design team.
Expensive, but as always A1+ quality. What a great company, love my X series.
Great, ill wait on 750W as it will hopefully be £20 less. has everything we need!
They make for so many companies now, Cooler Master, Corsair, XFX, the list goes on and on! Still i always go for the company themselves, even though they cost normally a bit more.
i got 750w version, is that as good as this one?
My S12 II 850W EVO unit is very load, even with load at 280 – 300W to PSU, fan ramps ups very quickly and it’s pretty loud.
My PC with 3770K @ 4.5GHz and GTX 780 @ 1150/1600MHz pulls ~ 440W from the wall in Crysis 3 (measured with watt meter), that’s ~ 370W from PSU and fan hits very high rpm, I would say max.
It’s very annoying and I would recommend anyone to look elsewhere if thy want a silent PSU, this one is a jet.
I really don’t know how your unit (kitguru) and also one on jhonnyguru review was so silent, because there are many issues on the internet with people complaining about noise on S12 II units.
Other than that it’s a very good PSU, it’s a shame that a bad fan / fan profile combo ruined such a great picture.
Yes it is.
I have only 520W EVO but I hope it’s at least good with only i5 4590 and 650ti boost.
